here clara hopper and clara forth are analyzing the water samples that they took yesterday clara really enjoys this part of her research. before me a moment it's always exciting to look at things under the microscope. there's containers of water don't seem very interesting at 1st but then you run the water through the filters sit down and take a closer look and there are lots of really beautiful shapes. and i really enjoy the swag. there. of course there's a serious side to this research the scientists are studying the impact that humans have on the environment. right now marion is on her way to the local air filter to carry out some tests. these high powered radio telescopes gather data from space now the researchers are going to launch a drone that's full of sensitive sensors that measure weather conditions in the drone data will supplement the information that's gathered by marian's balloon device. marian says that she's impressed with this kind of technology. it's told it's great i think it's exciting and all of our researchers contribute something different to these projects and i

meanwhile marine biologist clara hopper is packing for a trip to the arctic ocean she hopes that the weather will be good some good fun said he. best it's always best to be out in the water when there's no wind and the equipment has to be lowered and raised versatile if those as buffeted by the wind it's harder to keep everything steady but i understood you to heighten and certainly like weather and the forecast for tomorrow looks quite abandoned. better from all and you can schoolgirls. doctoral students caravan for also go along on this trip the 2 scientists are getting their testing equipment ready now so they won't have to do it on board the ship tomorrow. they'll try. to collect as many water samples as possible. so couldn't when there was a temperature is just below 0 degrees celcius is the chart from. this data is from yesterday and the surface water is just around 0 and below that it drops down to minus 0.3. the weather forecast turns out to be correct clear skies not much wind and a carm sea. klara outlines the focus of their research. that's all that's futile we're studying

hopper is preparing a water collection container. she and her colleagues use a steel cable to lower the device which will take water samples of various depths. clara is particularly interested in finding samples of plants and also called micro algae. as soon as they bring the container back up they start analyzing its contents. it's a good thing that they prepared the individual files in advance because it's cold out here. and them with this thing at the end of the day with freezing. but they put up with the weather because the study of micro provides crucial data. is required we didn't put these organisms produce about half the oxygen and they have the atmosphere is well you know every 2nd breath that we take wouldn't even say also absolutely a lot of carbon dioxide it's 5. carbon dioxide contributes to climate change. back at the research facility marion. he's getting ready to fill her weather balloon with helium. she's done this hundreds of times but she still gets a kick out of it. the blue moon is made of highly elastic rubber it will have to withstand enormous fluctuations in air pressure as it rises through the atmosphere. all set. it's ess
